Regression Analysis > Linear Relationship. What is a Linear Relationship? A linear relationship means that you can represent the relationship between two sets of variables with a line (the word “linear” literally means “a line”). In other words, a linear line on a graph is where you can see a straight line with no curves.

Linear relationships such as y = 2 and y = x all graph out as straight lines. When graphing y = 2, you get a line going horizontally at the 2 mark on the y-axis. When graphing y = x , you get a ...

Linear relationship is a statistical term used to describe the relationship between a variable and a constant. Linear relationships can be expressed either in a graphical format where the variable ...

The graph clearly shows that the slope is continually changing; it isn’t a constant. With a linear relationship, the slope never changes. In this example, one of the fundamental assumptions of simple regression analysis is violated, and you need another approach to estimate the relationship between X and Y.

linear relationship: A relationship of direct proportionality that, when plotted on a graph, traces a straight line. In linear relationships, any given change in an independent variable will always produce a corresponding change in the dependent variable. For example, a linear relationship between production hours and output in a factory means ...

Another special type of linear function is the Constant Function ... it is a horizontal line: f(x) = C. No matter what value of "x", f(x) is always equal to some constant value. Using Linear Equations. You may like to read some of the things you can do with lines:

Linear equations like y = 2x + 7 are called "linear" because they make a straight line when we graph them. These tutorials introduce you to linear relationships, their graphs, and functions.

A linear relationship exists when two quantities are proportional to each other. If you increase one of the quantities, the other quantity either increases or decreases at a constant rate. For example, if you get paid \$10 an hour, there is a linear relationship between your hours worked and your pay.
